Power banks are available in a variety of sizes and forms to accommodate a wide range of needs. A power bank’s power output, capacity, ports, and TSA approval all contribute to its suitability for a particular application. However, the essential characteristic to consider when shopping for laptop power banks is the output power.
Because each laptop model requires a different amount of power output, it is critical to check the power input specifications of your laptop prior to purchase. For example, some Macbooks consume 29W, 30W, 45W, 60W, 61W, 85W, 87W, and 96W of power. Moreover, laptops with faster processing speeds and bigger screens often use more input power than ultraportable laptops, which in turn use less input power.
If you choose a power bank that is insufficient for the power requirements of your laptop, charging will be prolonged or will not occur at all. Bear in mind, that just because the power bank can deliver a high amount of power does not guarantee that the laptop will charge quickly.
When deciding how to charge a laptop, it’s important to consider the ports available on the device. To charge a laptop optimally, your port must be capable of transferring the necessary amount of power. When compared to USB-A, USB-C is more capable of accomplishing the job required. If your laptop does not have a USB-C port, you should opt for a power bank that includes both a DC cable and a port.
If you are traveling by airplane, keep in mind that your power bank should have a capacity of less than 20000mAh and less than 100Wh and a clear label/imprint indicating the charger’s capacity (mAh and Wh).
1. Best overall: RAVPower 30000mAh
If you’re looking for a reputable brand to purchase a power bank from, RAVPower should be one of your options. What distinguishes this brand is that their products are not only of high quality but they are also reasonably priced, and the RP-PB232 is no exception.
This power bank has a capacity of 30000mAh and 90W, but what makes it so appealing is that it is housed in a very small body, which we will discuss further below.
Due to the USB-C 90W power output, you can also charge laptops with higher power consumption, such as the 15-inch MacBook Pro. RAVPower claims that the RP-PB232 can charge a 15-inch MacBook Pro from 0% to 40% in just 40 minutes, which is quite impressive.
It is worth noting that it will take less time to charge it fully if you turn off the laptop.
If you’re wondering how many times a 30000 capacity can charge your phone, the answer is up to 6.3 times for an iPhone 12, 4.5 times for a Galaxy S20, and 2.5 times for an iPad Pro, which is more than enough to get you to the next wall plug.
In terms of charging speed, the RP-PB232 has surpassed all expectations, as RAVPower incorporated Power Delivery technology to determine the maximum amount of power that can be drawn from the power bank and delivered to the device. This USB-C power bank delivers 65W PD and 18W iSmart USB-A output while simultaneously charging two devices.
If you own a Samsung Galaxy S20 or S20+, this power bank will benefit you more because it features a Programmable Power Supply (PPS) that allows you to charge these devices in one hour.
Additionally, the USB-C port on the RAVPower RP-PB232 supports 60W input, which means the power bank will charge in just 2.5 hours. Furthermore, the USB-A power bank boasts iSmart technology to protect both the power bank and the devices it charges.
iSmart provides ten comprehensive, all-encompassing protection options, including over-discharge protection, surge current protection, surge voltage protection, over current protection, short circuit protection, high-temperature protection, safe reset mechanism, reverse connection protection, and EMF protection. The RP-PB232 is powered by LG 21700 High-Density batteries, ensuring the product’s high quality and safety.
When it comes to RP-PB232 aesthetics, it is clear that RAVPower put a lot of thought into it. Even though the product has a simplistic appearance, the details are intriguing. Ports, LED indicators, and the power button are all positioned in the corner, making it more convenient to use; you don’t have to spin the power bank to find the power button or LED indicators after plugging in the cables.
With dimensions of 5.9 x 3.4 x 1in (15 x 8.7 x 2.5 cm) and a weight of 19oz (540g), it occupies only one backpack pocket and adds less noticeable weight to your travel or camping bag, making it a very easy to carry the power bank. It should be noted that the RP-PB232 is a 108.9Wh power bank, which exceeds the 100Wh limit, and you are not permitted to bring it on flights without prior approval.
2. Highest Power Output: MAXOAK 50000mAh (130W Max)
This hefty external battery works with most laptops (but not Macs!) and features 6 output ports: one 20V/5A port for laptops, one 12V/2.5A port for digital cameras, two 5V/2.1A, and two 5V/1A for smartphones and other battery-charged devices.
Multiple devices can be charged at once, which is very handy if you have a laptop and a phone that need juice at the same time. Or if you too have friends that never bring their own power banks and always rely on you.
The size of this battery is 8.1″ x 5.3″ x 1.3″ (20.6cm x 13.5cm x 3.3 cm), which is quite a good ratio for this amount of power. But in case it’s difficult for you to visualize its size, here’s an image with a person handling it in real life.
And at 2.77 lb (1.2 kg) it has a decent weight, although you wouldn’t want to take it jogging.
The MAXOAK 50000mAh comes with the following items included (besides the battery itself):
- Battery charger
- DC cable
- 14 (!) different connectors
- A carry-on bag
- A message card
3. Highest Capacity: Renogy 72000mAh Laptop Power Bank
Although not as famous as other brands in this list, Renogy, delivered a sound product in the Renogy 72000mAh. It’s one of the few power banks that’s been made primarily for laptops. With its high-end capacity, it can power almost all laptop models, with the exception of those that operate with a DC current over 62.7W.
One of the most appealing features of the Renogy 72000mAh is the fact that it comes with two DC outlets; a Laptop output port, and a cigarette lighter port. So if you’re into activities that require the use of two laptops at the same time, through a car inverter to laptop adapter, this is could be one of the best alternatives. Besides the 2 DC outlets, it also features one USB-A port, two USB Type C ports (one of these supports PD), and one 12V/15A cigarette lighter port for small medical equipment or devices with an extra car power inverter.
In terms of size, it comes in at 9 x 4.9 x 1.7 in (22.86cm x 12.45cm x 4.32cm), and it weighs 52.8 oz (1496 g). Despite not being the lightest and most compact on the list, it is highly portable considering its huge capacity.

4. Most Rugged: Goal Zero Sherpa 100PD
If you’re looking for a high-quality, compact power bank with an adequate number of ports, the Goal Zero Sherpa 100PD is a decent choice.
This lithium-ion power bank features a capacity of 25600mAh and a power output of 94.7Wh. This amount of energy is enough to charge a POV camera 19 times, a smartphone seven times, a tablet three times, and a laptop 1.5 times. Moreover, if you’re wondering whether you’re allowed to bring 100PD on a flight, the answer is yes, as the TSA’s limit is 100Wh.
This power bank has three ports: two USB-A (12W) ports and one USB-C (60W) port.
Two USB-A ports allow you to charge two devices simultaneously, such as fitness trackers, GPS devices, and micro/lightning phones. If your laptop is equipped with a USB-C port, you can charge it by connecting it to the USB-C port on the power bank.
It’s critical to keep in mind that this port delivers a maximum of 60W, which means that charging the laptop should be done when it’s not in use. However, if you have an ultraportable laptop, such as a 13-inch MacBook, with a low power requirement, you can charge and run the laptop concurrently.
The Sherpa 100PD features Power Delivery technology for quick charging via the USB-C port. In summary, Power Delivery technology enables the power bank and the device it charges for communicating with one another and determining the maximum amount of power that can be drawn from the charger to the device in order to speed up the charging process.
Another fascinating aspect of Power Delivery is that it enables power to flow in both directions without regard for circuit or connection orientation. So, for instance, if you use a USB-C charging cable to connect two smartphones that support Power Delivery, one can charge the other and vice versa.
To ensure safety, Goal Zero has regulated all three ports on this power bank to ensure constant flow without overheating, short-circuiting, or overcurrent.
Furthermore, If your devices support wireless charging, you can enjoy the convenience of this feature with Sherpa 100PD without the need for cables.
The gleaming and elegant Sherpa 100PD is a surefire way to win your heart when it comes to appearance. The body of this power bank is plastic, but it would seem to be aluminum, and it weighs 1.4 pounds.
This material has a number of advantages and disadvantages, and the customer must decide whether it is beneficial or detrimental. While a plastic power bank is lighter than an aluminum one, the aluminum body is more impact-resistant and has the potential to survive in harsh environments. This power bank measures 7.5 x 3.7 x 1.0 in (19.05 x 9.4 x 2.54 cm), slightly larger and thicker than today’s smartphones while remaining small enough to fit in a backpack.
Unlike some power banks, which display the remaining charge via green and red LED lights, this power bank features an LCD display that shows the exact amount of juice remaining in the battery, which is an added benefit of this product.
5. Most Compact: Anker PowerCore+ 26800 PD
Anker is one of the top brands when it comes to power banks. This model is a good fit for anyone that wants to power their laptops, especially MacBooks or other USB Type-C devices. One of the features that stands out for this battery is it’s fast charging time. At only 4.5 hours, it’s one of the fastest on this list. A great advantage if you’re in a hurry.
As a plane-safe device, that is also small and nimble, this is a great option for traveling. At 1.3 pounds (590 g) it can easily be carried in a backpack and at 6.5″ x 3.1″ x 0.9″ (16.51cm x 7.8cm x 2.2cm) it might even fit in a pocket.
Although perfect for Macs, the Anker PowerCore+ 26800 PD is not compatible with a series of laptops such as HTC 10, Dell XPS series, Lenovo ThinkPad 470s, ThinkPad X1, HP Spectre, and the Huawei MateBook. And for some other models, it doesn’t support high-speed charging.
6. Best with AC: RAVPower 20000mAh
With an AC outlet, this RAVPower power bank is ideal for those whose laptops lack a USB-C charging port. In terms of power, the RP-PB054 provides the user with a capacity of 20000mAh and a power output of 74Wh, which will keep them fully charged while they are outdoors or without access to electricity.
Furthermore, this power bank has 74Wh, which is less than the 100Wh flight limit, so that you won’t have any issues during your flight.
The AC output, which is the primary advantage of this product, can reach up to 80W. This power output can be used to charge your MacBook Pro, Nintendo Switch, desk lamp, and other compatible devices. Bear in mind that you must first press and hold the power button for approximately 3 seconds to activate the AC outlet.
As with the majority of USB-C ports on laptop power banks, the RP-PB054 supports Power Delivery (PD). If you’re wondering which port will be used to charge the power bank, it will be the USB-C port, which functions as both an input and an output. When using 30W PD input, the power bank can be recharged in 3.1 hours, which is 60% faster than most power banks that employ USB-A input.
Additionally, USB-A ports support Qualcomm’s Quick Charge 3.0 technology, which operates at 12V, 1.5A. To summarize, if your device is compatible with Quick Charge 3.0, you can charge it up to 80% in just 35 minutes, which is quite impressive.
The RP-PB054 incorporates elements of beauty, knowledge, and experience into its design. There is no doubt about the beauty of this product; as with other factors, RAVPower has equipped a fan at the button of the RP-PB054, which is a demonstration of employing knowledge and experience in product design.
In addition, these air vents on the bottom of the power bank provide advanced temperature control for extended use.
Although the AC output is located near the power button and other ports, you can still use them while connecting the adapter to an AC outlet.
This model has dimensions of 6.9 x 6.9 x 14.6 inches (6.9 x 14.6 cm) and weighs 1.45 pounds, making it the ideal travel companion. To ensure maximum customer satisfaction, RAVPower includes a carrying pouch and a USB-C to USB-C cable in the box.
7. Krisdonia 50000mAh
NJF-5X is a monstrous laptop power bank when it comes to capacity and port flexibility. With 50000mAh and 185Wh, you’ll never have to worry about the battery level of devices in protracted journeys to faraway locations. Unfortunately, this benefit comes at a cost since the device is not Transportation Security Administration (TSA) approved for use on flights due to its high power output.
This power bank’s exceptional quality and safety are ensured by its compliance with UL1642 and UL2056 standards. NJF-5X is made of Li-Polymer battery cells and includes six security features to ensure safe use and over 1000 recharge cycles.
With a battery capacity of 50000mAh and 185Wh, the NJF-5X can recharge a 65W laptop about 2.5 times and a smartphone about 11-18 times. To charge this power bank, just connect the adapter to the DC-IN port, and it will charge in seven hours due to the rapid charge function, which saves you 60% of your time.
Pass-Through charging is supported by this power bank model, allowing you to charge both the power bank and the devices connected to it at the same time. This feature eliminates the need to charge each device separately, which is particularly useful if you only have access to a single power outlet for a limited amount of time.
Always keep in mind that the function can only be accessed by pushing and holding the button for two seconds while the power bank is charging.
The DC-OUT connector that Krisdonia equipped the NJF-5X with is the product’s major benefit. This port accepts input voltages ranging from 5 to 20 volts and can be used to charge your laptop directly without the use of a laptop charger.
Before charging your laptop or other devices via the DC connector, double-click the power button to adjust the DC voltage. Krisdonia has included 28 connectors NJF-5X that are compatible with virtually any laptop brand.
Because the power bank is capable of charging laptops with power requirements of 90W to 100W, you should have no issues using your laptop while it is charging. However, it is recommended to shut down the laptop to expedite the recharging process.
Note that, If the power bank goes off after one minute, it’s because your laptop’s current draw is too high. So please refrain from using your laptop while charging. Another crucial point is to double-check your laptop adapter’s label. If the output exceeds 4.7A, overcurrent may occur. As a result, we do not recommend using this power bank to recharge your laptop.
As previously stated, this laptop power bank has two USB-A charging ports for devices such as smartphones and cameras. These two ports are equipped with Quick Charge 3.0 technology, which enables fast charging of devices.
Take note that your devices must be compatible with Qualcomm’s Quick Charge 3.0 technology in order to make use of the luxury that comes with this technology.
In terms of size and weight, the NJF-5X is small and lightweight, measuring 7.6 by 5.9 by 1.1 inches and weighing 2.55 lbs. Because this power bank contains a plethora of cables and connectors, Krisdonia included a bag in the package, which is a thoughtful touch.
8. Omnicharge Omni20+ 20000mAh
Are you a power user in search of a versatile power bank? In that case, we recommend Omni20+. This power bank is armored to the teeth in terms of ports and power output and is considered a holy grain by some.
Omnicharge has a capacity of 20000mAh and 71Wh, ensuring that you will have enough power to charge anything from smartphones to GoPros and drones.
Apart from physical ports, the Omnicharge Omni20+ features a +10W wireless charger that is compatible with any device that supports wireless charging. While the majority of compact laptop power banks only include USB-C ports for laptops, the Omni20+ encompasses AC, DC inputs for added convenience.
The USB-C port offers a maximum power output of 60W, which is typically found on 13-inch and some 15-inch laptops. With a capacity of 20000mAh, you can charge a smartphone five times, an action camera ten times, a DSLR five times, a drone once or twice, and a 15-inch laptop once.
It is worth noting that USB-C supports Power Delivery technology, resulting in rapid charging. Furthermore, the Omni20+ is outfitted with Pass-through Charging to keep itself, and the devices connected to it charged at all times.
Omni20+ is kept safe in a 5.0 x 4.8 x 1.1 inch (12.7 x 12.2 x 2.7 cm) body by Omnicharge. The matte finish gives this power bank a classy appearance, and the build quality is what we would expect from a well-known brand. Furthermore, with a weight of 1.35 lbs (611g), it is very portable.
One of the best features of this product is its display. You don’t have to guess how much power your devices consume or how much power your Omnicharge provides. The OLED display allows you to monitor the power levels of your device better and know what you need to keep fueled throughout the day.
The company paid close attention to detail, assigning a dedicated button to each USB-A button, which is very practical. However, this design is not without flaws.
As a result of this design, all ports are not on the same side, resulting in poor cable management and the necessity to spin the power bank to find the correct port. As previously stated, the Omnicharge Omni20+ has a 71Wh capacity and is TSA approved so that you can bring it into the flight without prior permission.
9. Anker Powerhouse 200
